Upgrade ASUS X555S: what can be improved?

The main way to extend the life of a laptop is replacing HDD with SSD And increasing RAM. Let's consider both options in detail.

1. Replacing the hard drive with an SSD

Standard HDD 5400 rpm in X555S - the main bottleneck. After installation SSD (For example, Kingston A400 240 GB) the laptop turns on for 10–15 seconds (against 40–60 seconds on the HDD), and programs open instantly. Supported formats:

  • 📏 2.5" SATA III (up to 1 TB) - the best choice in terms of price/performance.
  • 🔌 mSATA (if there is a free slot, check the motherboard model!).

⚠️ Attention: In some revisions X555S after replacing HDD with SSD System restore stops working (no hidden section Recovery). Create a bootable USB flash drive in advance with Windows 10 LTSC — it works easier and more stable on weak hardware.

2. Increase RAM

The laptop supports up to 8 GB DDR3L (1600 MHz), but there are nuances:

  • 🔍 Check current memory: if installed 1 stick 4 GB, add a second one (dual mode will speed up work by 10–15%).
  • 🚫 Do not combine planks from different manufacturers - errors are possible BSOD.
  • 🔧 To access the RAM slots you need to remove the entire bottom cover (fastened with 11 screws).

Which memory to choose for ASUS X555S?

Recommended models:

- Crucial CT51264BF160B (4 GB, 1600 MHz) - a reliable budget option.

- Samsung M471B5173EB0-YK0 (4 GB, original for many ASUS laptops).

- Kingston KVR16LS11/8 (8 GB if you need maximum performance).

Important: Before purchasing, check the supported maximum RAM for your motherboard revision (eg. X555SA may not see 8 GB).

3. Other possible improvements

Less obvious but useful upgrades:

  • 🔋 Battery replacement: original ASUS C11P1305 (44 Wh) costs ~2 thousand rubles, but you can find analogues cheaper.
  • 📡 Replacing the Wi-Fi module: standard Qualcomm Atheros QCA9565 (Wi-Fi 4) can be changed to Intel 7260 (Wi-Fi 5) for better speed.
  • 🖥️ Connecting an external monitor: through HDMI 1.4 resolution up to 1920×1080@60Hz.

Typical ASUS X555S problems and how to solve them

Even with careful use X555S Over time it begins to "glitch". Here TOP-5 problems and ways to eliminate them:

1. The laptop gets very hot and slows down

Reasons:

  • 🧹 Dust in the radiator (even without a fan the heat sink gets clogged).
  • 🔋 Dried thermal paste (after 5–7 years of operation).
  • 🖥️ Background processes (For example, Windows Update or mining viruses).

Solution:

  1. Clean the radiator with compressed air (without disassembling the laptop).
  2. Replace thermal paste with Arctic MX-4 (apply a thin layer!).
  3. Disable unnecessary services: click Ctrl+Shift+Esc → Autoload → disable everything except the antivirus.

💡

If your laptop overheats while charging, try using the original power supply ASUS ADP-65JH BB (65 W). Cheap analogues often produce unstable voltage, which leads to throttling.

2. Wi-Fi or Bluetooth does not work

A common problem after updating Windows. Corrections:

  • 🔄 Uninstall the driver in Device Manager → Network adapters and reboot.
  • 📥 Download the driver from ASUS official website (choose model X555S and Windows version).
  • 🔧 If it doesn’t help, check the connection of the antennas to the Wi-Fi module (they might have moved away).

3. Doesn't turn on after updating BIOS

⚠️ Attention: BIOS update on X555S is fraught with “bricking” due to power failures. If the laptop does not turn on after flashing the firmware, try:

  1. Disconnect the battery and power supply, hold down the power button 30 seconds.
  2. Connect a known working power supply and try turning it on.
  3. If it doesn’t help, you need a programmer to flash the BIOS chip (contact the service).

4. Touchpad or keyboard does not work

Reasons:

  • 🔌 The train comes off (often after disassembling the laptop).
  • 🦠 Virus or driver failure (check in Device Manager presence of exclamation marks).
  • 💧 Liquid ingress (keyboard or touchpad replacement required).

💡

If the touchpad stops working after a Windows update, roll back the system or install a driver ASUS Smart Gesture from the official website. Automatic updates via Windows Update often install incompatible versions.

5. Battery drains quickly

Battery life X555S - 3–4 years. If the laptop is powered for only 30–60 minutes:

  • 🔋 Check for wear in Command line: enter powercfg /batteryreport and open the generated file battery-report.html.
  • 🔄 If the capacity is smaller 40% from the original - replace the battery.
  • ⚡ Calibrate the battery: completely discharge the laptop, then charge until 100% no breaks.
